I have a decent stock from which to pick matched pairs Nic but it is good that you have pointed this out. When I get around to knocking up a pair of these Pushme-Pullyous I will put results up on my webpage.

Why not use a 350-400V HT supply and stack the things as SRPP cap coupling a mains toroid between the top 6C45 cathode and 0V ? Battery bias with a chunky NiCad or NimH on the cathode of the lower valve . A 230:6-0/6-0 mains toroid with the secondaries in series will provide about a 3k impedence into an 8r load . I suppose there are plenty of possibilities ! That reminds me , I must try building something with the 7788's !
